PATENT HENRY RUPPEL, OF CLEVELAND, OH lO GASOLINE OR VAPOR STOVE.

SPECIFICATION forming part of Letters `Il-atent No. 495,063, dated Apt-il f1 1,?1893.

Application filed February 25, 1892. l Serial No. 422,767. (No model.)

To all whom it r11/ty concern:

Be it known that I, HENRY RUPPEL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Iniproveinents in Gasoline or Vapor Stoves, of which the following is a f ull, clear, and oompiete description.

My invention relates to the burners, constructedwith a series of air tubes and slotted burner tubes so arranged in connection with a hood or cap, that an intense blue dame is projected upward from the tire ring and disseminated by means of the distributing cap over the bottom of any cooking utensil that may be resting upon the grate.

It also relates toa tubular ring or channel constituting the supply tube and the fire ring: also the overflow chamber all surrounding the lower terminals of the slotted burner tubes. rlhe supply tube is connected with the fire ring by an annular opening and the overflow chainberis supplied with a drip cup as hereinafter shown.

The improvement likewise pertains to the peculiar means for regulating the oil supply.

That the invention may be seen and fully understood by others reference will be had to the following speciiication and annexed drawings forming a part thereof.

Figurel is avei'tical section of myimproved hydrocarbon burner on the line z. e. Fig. 3; Fig. 2, a cross section on the line y. Ay. Fig. 1, in connection with the supply pipes and showing the means for producing an even flow of oil; Fig. 3 a top view of the distributing cap and burner; Fig. 4 a View of the stove with my improvements attached thereto. Figs. 5 and 5' are views illustrating the burner tubes as being slotted vertically instead of horizontally as in Fig. 1.

Similar letters of reference designate similar parts in the drawings and specification.

The inner tube A, Figs. 1, 2, and 3 is sui'- rounded by the tube B, Figs. 1 and 2, forming an annular chamber between the two tubes. The air arising through the inner tube A disseminates the odoriterous gases, which emanate from the burning oil, over the surrounding flame where they are rendered innoxious, thus obviating a very disagreeable feature of the ordinary gasoline or vapor burner, and also assists in distributing the iianie evenly over the bottom of the superimposed utensil. kThe air that passes upward through the annular chamber, formed by the tubes A and B, commingles with the air arising from the tube A, for the purpose o f f urnishing oxygen to the tlaine and intensifying the same, at the top. Outside of the tube B is the slotted burner tube C, Figs. 1, 2 and 3 and enveloping the burner tube O is the burner tube D, Figs. 1, 2 and 4, of similar oonstruetion. The slotted burner tubes C and D extend down from the top of the burner alittle more than half the length of the tubes A and B.` Depending from the top of the burner tube D is the cap E, Figs. l, 3, and 4. Fioin the base or' the chimney C and extending downward until its base is in a line with the lower extremities of the tubes A and B isl the tube F, Figs. l, 2 and 4. The legs G Fig. 1 of the distributing cap G, Figs. 1 and 3, are received into an oval depression at the top of the burner tube C, as shown in Fig. 1.

The distributing cap G is a casting coni posed of a series of rings g, and the braces g', being otherwise open except between the third and fourth rings from the center Fig. 3, which are joined together all the way around by the web g2 for the purpose of catching any dust or other matter that might otherwise fall v between the burner tubes O and D. The tubes and slotted chimneys may be held together by the braces B', Figs. 1 and 2 or by any other suitable means.

The burner tubes C and D may each be cast solid with the beads D Figs. 1 and 2 and then sawed between the annular bars C Fig. l, leaving said bars connected only by the beads D', or they may be formed in any other suitable manner as by having the slots formed in the original casting. The outer circumference of the burner tubes O, and the inner circumference of the burner tubes D are smooth and even while the coneavity of the bars C and the beads D appear on the inside of burner tubes O,and on the outside of burner tube D, all of which is fully illustrated in Fig. 1. The advantage derived from using slot- ICO ted instead of perforated burner tubes is the strong steady iiame resulting therefrom. In place of the annular bars as in Fig. l, vertical bars I-I Figs. 5 and 5^ may be substituted having the interstices as before stated, said bars being held together by the annular' beads I. The shape of the bars in either case is iinmaterial.

Surrounding the tubeF and attached thereto is the overliow chamber J Fig. l which is provided with the iiange J' to receive the Supply tube K, Figs. l and 2. The fire ring L. is formed and arranged below the supply tube K, having the annular slot K', opening therein, or the base of the supply tube K is prolonged toward the center and forms the ire ring L. The annular slot K', Fig. l, is the only means of communication between the supply tube and the fire ring and since said slot is very small or narrow the flow of oil from the supply tube into the iire ring is graduated to the right proportion and the flow is regular. In place of the slot K', perforations may be substituted. The supply tube K fits closely around the base of the burner tubes D, and in connection with the overflow chamber J, completely closes the space between the bases of the burner tubes C and D.

The oil flows from the supply tube K through the slot K' into the fire ring L Where it is ignited through the port L' Figs. 2 :fnd 4. More or less overilow will result from the burning oil in the fire ring L, which overow will be received by the chamber J, where it will burn, heating up the oil in the supply tube K and the fire ring L. This combined ame is carried upward with much force by the air entering thebase of the outer tube F and passing between the base of the burner tube C and the air entering from the outside under the cap E, and between the base of the burner tubes D. When the ame reaches the top of the burner it is an intensely, hot, blue flame and is disseminated over the base of whatever utensil is on the grate M Fig. 4, by the distributing cap G and the Idrafts of air arising through the tubes A and B. After the flame is eXtinguished the excess of oil remaining in the chamber J Hows through the pipe N Figs. l and 4 into the can O, where it lnay be drawn olf a1; will. The can O is intended to hold the surplus oil from all the burners of a single stove and is attached thereto at any convenient point, or each burner may be provided with an individual cup O' indicated by the dotted lines Fig. l in which case the contents of said cup will ignite and supplement the heat above.

The two pipes I), Figs. l, 2 and 4, carry the oil from the regulating chamber Q Figs. 2 and 4 to the supply tube K. The chamber Q receives oil through the pipe R Figs; 2 and 4.

from the reservoir S Fig. 4. and the pipe R', carries the iuid on to the next regulating chamber. In the chamber Q Fig. 2 is the cell T provided with the small openings T', one into each of the pipes P, and the opening into the chamber Q, shown closed by the needle valve U. The progress of the liquid through the three small openings in the cell T is necessarily very even and regular and the amount is easily regulated by the needle valve U. The stop U', is for regulating the needle valve. f

What I claim as my invention, and desire to secure by Letters Patent, is-

B. forming an annular chamber,in combination, with the slotted burner tubes forming a secondary annular chamber surrounding the tube B, the supply tube K, and burner ring at the base of the tubes C. and D, a distributing cap G, surmounting the tubes, and the hood E depending from the outer slotted tube D, substantially as and for the purpose set forth.

2. In a gasoline or vapor stove, the slotted burner tube C, surmounted by the distributing cap G, in combination with the slotted burner tube D, surmounted by a depending hood, and the annular supply-tube K, at the base of the annular chamber formed by said slotted burner tubes C and D, in the Inanner substantially as and for the purpose set forth.
